Image Resizer 1.0.0: HEIC Support and a Pro Plan

Image Resizer 1.0.0 is now on the Chrome Web Store, and the Firefox version is in Mozilla's review. It's the first update since 0.3.0, and it brings two main changes: the extension can now open photos straight from an iPhone, and there is now a Free plan and a one-time Pro upgrade. This post covers what's new, what stays free, and what changes if you already use 0.3.

HEIC and HEIF photos open directly

iPhones save photos as HEIC by default, and until now you had to convert them somewhere else before Image Resizer could read them. In 1.0.0 you can drop a .heic or .heif file into the extension like any other image. The decoder ships inside the extension, so the conversion happens on your device like the rest of the work.

The full list of formats Image Resizer can open is now JPG, PNG, WebP, BMP, TIFF, HEIC and HEIF. You can save the result as JPG, PNG or WebP.

What stays free

The Free plan has no trial period and needs no account. It includes:

• All 22 platform presets for Instagram, Facebook, X, LinkedIn, YouTube and WhatsApp
• Custom dimensions up to 16000 × 16000 px, with an optional aspect-ratio lock
• Stretch, Fit and Crop modes, with a 9-point focal point for crops
• A target file size, such as 200 KB, where the extension adjusts quality to reach it
• Background color for Fit mode: white, black, transparent or a custom hex value
• Batches of up to 5 images per run, downloaded one by one or as a single ZIP
• Up to 3 saved profiles
• Drag and drop, the file picker, pasting from the clipboard, and Resize this image in the right-click menu
• Light and dark themes

If you have one photo that has to fit a size limit or a platform's dimensions, the Free plan does the whole job.

What Pro adds

Pro is a one-time purchase of €7.99, with no subscription and no renewal. It adds:

• Export packs. Select several presets and get every version of an image in one ZIP, for example an Instagram post, a story and a LinkedIn image from the same photo.
• Unlimited batch size. Process as many images in one run as you need.
• Up to 20 saved profiles.
• Up to 5 browsers. One Pro key can be activated on up to 5 browsers you use.

To activate it, open the extension, click Have a key? and paste your license key. Payments are processed by Lemon Squeezy. Prices and checkout are on the pricing page.

If you used 0.3

0.3 had no plans, so a few things that were open to everyone now sit in Pro. On the Free plan in 1.0.0:

• Exporting a pack of two or more presets at once needs Pro. Single-preset exports, including ZIP downloads of a batch, stay free.
• A batch run takes up to 5 images. If you drop more, the first 5 are added and the extension tells you how many were left out.
• You can save up to 3 profiles.

Everything else you used in 0.3 works the same way on the Free plan.

What connects to the network, and when

Image Resizer resizes, crops, converts and compresses images on your device with the browser's OffscreenCanvas API. Your images are not uploaded to UnifyBrowse or anyone else. The extension doesn't ask for permission to read the pages you visit. A few things do use the network, and it's worth knowing which:

• Resize this image in the right-click menu downloads that one image from the site that hosts it, then processes it in the extension.
• Activating Pro sends your license key and a label naming your browser and operating system, such as "Image Resizer · Chrome 130 · Windows", to UnifyBrowse's license server at ir.unifybrowse.com. The server returns an activation ID for that browser. While a key is active, the extension checks it with the same server by sending the key and that activation ID, and deactivating sends them too. No images are sent.
• Installing the extension opens a welcome page on unifybrowse.com, and larger updates such as this one open an update page. Both addresses include a random install ID that the extension creates and the version number. Uninstalling opens a goodbye page with the same ID.

If you're on the Free plan and never enter a key, the extension doesn't contact the license server.

Get it

Add Image Resizer to Chrome. If you already have it, Chrome updates it to 1.0.0 automatically. The Firefox version will be on Firefox Add-ons once Mozilla's review is done. To see what the focal-point crop and target file size do in practice, read Aim & Compress, our post about 0.3.
